The numbers are 91, 92 and 93.
31 and 3
93
Many, but not all. An example is 93. 93 is equal to 31x3 and not only 93x1. Another example is 63. 63 is equal to 21x3 and not only 63x1.
91+93+95+97+99 = 475
93 + 93
The numbers are 91, 92 and 93.
31 and 3
93
Many, but not all. An example is 93. 93 is equal to 31x3 and not only 93x1. Another example is 63. 63 is equal to 21x3 and not only 63x1.
91+93+95+97+99 = 475
93 and 42
To find how many numbers from 10 to 93 have the sum of their digits equal to a perfect square, we first identify the possible perfect squares within the range of digit sums. The digit sum of a two-digit number ranges from 1 (for 10) to 18 (for 93). The perfect squares in this range are 1, 4, 9, and 16. By calculating the digit sums for each number from 10 to 93, we can determine that the numbers with digit sums equal to these perfect squares are 10-19 (sum = 1, 4, 9), and some others up to 93, yielding a total of 38 numbers.
1 x 279, 3 x 93, 9 x 31
The factors of 279 are: 1 3 9 31 93 279These pairs of numbers, when multiplied, equal 279:(1, 279)(3, 93)(9, 31)
One solution is, 4! + 67 + 2 = 24 + 69 = 93
93 is the only composite factor of 93.
